DEVICE FOR CLEANING THE COOLING SYSTEM OF AN INTERNAL-COMBUETION ENGINE.

Application filed October 31, 1924. Serial No. 747,184.

This invention relates to a device for reconduit to the upper end of the radiator newing water in a radiator and an engine 1 whereby the upper end of the water for an automobile and has for its object the jacket of the engine is placed in open comprovision of a device which will cause a munication with the chamber 6 in the upli circulation of water through the radiator per end of the radiator. 60 and cooling jacket of an engine for ex- We replace the usual .radiator cap by pelling all foreign matter from the water means of a cup-shaped member 7 having jacket and radiator and for supplying the a flanged opening 8 in which is mounted a radiator with water. nozzle 9.

The outlet valves are turned on so that the water under ressure will flow through pipes 12 and-19, t ough the radiator and through the cooling jacket of the engine and be dischar ed throu h. the conduit 16. A suflicient circulation is provided until it is evident from the appearance of the water from pipe 16 that the tem is clear of foreign matter.
